Ooops! BBC accidentally publishes major Doctor Who S7 spoiler

Showrunner Steven Moffat has managed to keep a lot of details under wraps for the upcoming series of Doctor Who, but apparently the production office didn’t get the memo.

Spoiler ahead!

The cast list for the season seven return “The Bells of Saint John” has been released, revealing that the Great Intelligence (Richard E. Grant) will apparently have a role in the story.

Last seen in “The Snowmen,” the Great Intelligence is a classic Who villain that most recently tried to build an army of snowmen monsters in the Christmas-themed caper that formally introduced new companion Clara (Jenna Louise-Coleman).

What role will the evil entity have this time around? Who knows, but it’s pretty telling that all the promo material up until this point has avoided that little tidbit.

It’s possibly part of a reveal in the episode (could the malevolent entity have something to do with Clara’s mysterious identity?), or perhaps just a lingering bit of business left over from the Christmas special.

Regardless, we now know to keep an eye out for evil forces once The Doctor is back in action on March 30.

What role do you think the Great Intelligence will have this time around?
